The injury took some of the joy out of a dominant fourth quarter that led to a 121-96 victory and tied the Western Conference semifinal series at a game each.
Parker had been averaging 15.9 points during the postseason, a significant bump from the 10.1 he put up per contest in the regular season, before going down with 8:43 to play Wednesday.
"I definitely have to help out Kawhi (Leonard)", Aldridge said, via the San Antonio Express-News, after Game 2.
"So, that's a tough blow". We knew they were going to come out with some aggressiveness.
Spurs officials said the 16-year veteran will undergo an MRI on Thursday morning and will update his status after, but San Antonio coach Gregg Popovich said following the game that "it's not good".
San Antonio's victory celebration was tempered, however, by an injury to guard Tony Parker.
Parker, 34, is a four-time National Basketball Association champion and his absence even had an effect on the Rockets.
After the Spurs were blown out in Game 1, Parker responded with 18 points in 26 minutes before getting injured to help San Antonio rebound and even the series. This opens the door for more of Patty Mills and likely Manu Ginobili running the offense as well. But if Murray gets his start in game 3, maybe he will give the Spurs that something extra they need.
Thanks to Friday night's outcomes, all 11 second-round games have been decided by double digits.
"We have a great coaching staff and they do a great job of scouting, so we know all their guards, we know all their bigs", he said. Parker was a vision of his younger self providing the Spurs with 18 points and 4 assists. Game 4 is Sunday at 9:00 p.m. ET in Houston. Two huge voids as they go toe-to-toe with the high-powered Rockets in hopes of another trip to the Western Conference finals.
The Cavaliers are the only team since the Minneapolis Lakers in 1949 and 1950 to win their first seven playoff games in consecutive seasons. Leonard is averaging 27.5 points, 9 boards, and 7 assists so far in the series.
MVP candidate James Harden only scored 13 points on 3-of-17 shooting while being shadowed by Leonard most of the night.
Leonard showed in Game 2 that he may well be in a class now occupied by only LeBron James and himself. "You see the guys are smaller, and you want to go quick, but it's about being patient".
